Letters Patent No. 109.473, dated November 22,- 1870.

IMPROVEMENT; IN VENTILATORS'FOR HATS.

The Schedule referrd to in, these Letters Patent making part ofthe same.

I, WILMAM 11. WARBUn'rox, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in ventilators for Hats, of which the following is a. specification.

Nature und Object of the Iii-relation.

' Figure 1 isau edge-view of' the-band, illustrating a. feature of my invention.

lligurc 2 is a. vertical section, on the line 1 2, tig. v1; and

Figures 3, 4, and 5, views illustrating another featnre ot' my invention.

'General Description.

.ln lig. v1, b is a sweat-band, which is illustrated as combined wit-h the flexible strip a, for which Letters .Patent were granted me o'n the 11th day of December, Afl). 1860, reissued September 8, 1863; this strip, which may he made of' any suitahle'lnaterial, being perforated, connected to the sweat-band or to -the hat, or both, at the points .r .1', where the corrugations termina-te, the. sweat-band itself being,r plain between these points, and an open crescent-shaped space intervening between the sweat-baud and elastic strip, so that the latter will' accommodate itself to the wearer-s head, as described, in my aforesaid Ireissued patent.

.lhe elastic strip may he made from and constitute a. part of the-swcat-band in themanner illustrated in figs. 3 and 4. x

In this case, the sweat-hand is cutbetween the -points zva, midway'orftherealjont between its upper 4and lower edge, and the upper portion of the band thus cnt is severed at?, and the ends of the severed pieces are made to overlap eaCht-her, and are secured, together so as to form the desired elastic strip, (sce fig. 4,) ortho strip may be severed, overlapped and secured as shown in fig. 5, so that the joint may not oocurwhere the prominent part of the 4forehead tsin the'llat. j

I'prefer to secure the ends ot' the `ilexible strip to the hat, although the strip itself is ontsidethe sweatband; the strip, being much narrower than the band, covers but little of the forehead, and this little'is exposed to the jcool air owing to the perforatons; whereas, by the usual plan of arranging the strip inside the sweatbaud,thc latter must cover alarge surface of the forehead.

Claims. 1. .'lhe combination of a. sweat-band with a. flexible elastic strip a, arranged outside the band forthe purpose described.

2. A hat-band cut longitudinally, and contractedin length at one side of said cut, substantially as and for the purpose described. y

3. The flexible strip u, secured to.the hat tindex# tending through vertical slits :rx in the hatbaud, sul'istantia-lly as described. In testimony whereof, I Shave signed my name to this specification in the presence of two subscribing witnesses.
